Video Game-Like therapy could help older kids with lazy eye
NCT ID NCT07281742
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a home-based video treatment called Curesight for children aged 8 to 12 with amblyopia (lazy eye). The treatment works by showing videos where the stronger eye sees a blurred central area while the weaker eye sees the full clear image, encouraging the brain to use the weaker eye. The goal is to improve vision in the lazy eye. The treatment is already FDA-cleared for younger children, and this study aims to see if it works for older kids as well.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Curesight dichoptic video therapy (device)
- What this could lead to
- If it works, this could offer an effective at-home treatment option for older children with amblyopia who have not responded to standard therapies.
- What could go wrong
- This is a small early-phase study with only 30 participants, so results may not apply to all children. The treatment requires consistent use and may not improve vision in every case.
